SAFETY I-EGRSESHOIlir-CALK.

To all whom it may concern Be it known that I, STAFFORD BEVERLEY, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Safety Horseshoe-Calks, of which the following is the specification.

The invention relates to improvements in safety horseshoecalks, and the principal object of the invention is to provide an improved toe calk which will prevent the shoe from becoming stuck or caught in any of the various lodging places found in a roadway. i

X further object of the invention is to provide an improved calk which can be constructed and applied on the shoe at small expense to accomplish the above object.

With these objects in view the invention consists essentially in a horseshoe having the toe calk provided with a rearwardly directed and centrally disposed extension, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which;

Figure 1 represents a perspective view of a horseshoe fitted with my improved toe calk. Fig. 2 represents a longitudinal sectional view through the shoe, the section passing centrally through the extension. Fig. 3 represents a side view of the shoe. Fig. i l represents a side view of the shoe as applied on the hoof, showing the manner in which the improved toe calk operates when entered in a crevice.

In the drawing like characters of reference indicate corresponding parts in each figure. I

1 represents the ordinary horseshoe fitted with heel calks 2 and 3 and with the usual nail holes 4:.

5 represents the toe calk located in the usual position at the toe of the shoe, on the underside. This calk instead of being of the ordinary form, is fitted with a rearwardly directed, longitudinally disposed extension or guard 6 of the full length of the calk where it joins the same, the extension having the rear portion thereof formed with a rounded face 7 The distance which the extension passes back from the calk is approximately the depth of the calk. While I have shown this extension as applied on Specification of Letters Patent.

iApplieation filed April 16, 1915. Serial Iva-21, 727.

on the various forms of calks made without in the least departing from the spirit of the invention. To understand the use of it, I might mention that I have found that where the ordinary toe calk is used with no exten sion such as mine, that horses are very often crippled or injured through not being able to extricate their foot, owing to the calk slipping into an opening, such as appear in various forms in roadways. In order to make the matter clear, I might mention that the grid like covers of sewer manholes and the rails of street car tracks present openings in the roadway in which the ordinary toe calk of a horseshoe frequently lodges, and that owing to the construction of the present toe calk, it is a very easy matter for a horse to harm himself in event of the toe calk slipping into an opening presented by these articles. With the ordinary toe calk, which is the same as mine with the exception of the extension, it will be seen that once the toe calk enters such an opening and that when the heel of the hoof is raised, the calk is thrown into such a position that it naturally jams and will not allow the leg to free. lhis results veryoften in the laming or wrenching of the leg, so caught. Nith my invention On the calk, it will be seen that where the toe calk passes into an opening such as that 8 (see- Fig. 4L) in a grid 9, it is impossible for the calk to catch or jam, as the natural upward raising of the heel of the shoe, in the walking or running of the animal, rolls the toe calk out of the opening 8 and effectively prevents any jamming or catching.

It is considered that the explanation of the operation of this improvement will be readily appreciated from the example above given and especially shown in Fig. i of the drawing, and that the various other cases which might arise, will be readily understood without entering into a detailed eX- planation of them.

What I claim as my invention is;

1. A toe calk for horseshoes having a centrally disposed, rearwardly directed guard of the full depth of the calk where it joins the same and gradually decreasing in depth in passing backwardly, as and for the purpose specified.

2. The combination with a horseshoe and the toe calk' thereof, of a guard located cen trally of the calk and to the rear of the same and having the forward side thereof adjacent the'calk and of the full depththereof and the body thereof decreasing in depth in a gradual curve, as and for the purpose specified.
